This book contains a wide range of papers presented at the Symposium on Sustainable Land Use and Management of Soils in Arid and Semiarid Regions held in Cartagena, Murcia, Spain, 22nd to 26th September, 2002. Drylands are in the high-risk areas. Erratic rainfall, land degradation, inadequate technologies used, and inappropriate inputs result in unpredictable food production. The objective of the workshop was to widen our understanding of the nature and dynamics of vegetation growth and resilience and encourage the practice of sustainable management in the susceptible drylands. The book is a useful tool for land and water conservation researchers, educators, graduate students, policymakers, practitioners, and advocates interested in land degradation and sustainable use of soils in arid and semi-arid regions throughout the world.
